True or false: Transmission and transmission planning are only relevant to large, conventional electricity generators, and distributed renewables are only concerned with the distribution system, and never the twain shall meet. For many decades, this statement was profoundly true. But nowadays, with evolving technologies, improved planning processes and an expanded emphasis on integrated systems, the two previously disparate elements of our energy system are beginning to intersect.

So, doesn’t it make a lot of sense to store excess power from photovoltaics and other distributed generation resources to provide backup during outages? And, wouldn’t storage change the intermittent nature of PV on cloudy days and at night into a more dispatchable resource? Couldn’t it also provide other grid services to help maintain power quality and reliability?
